This will come as no big surprise, but the casting for the new Supergirl series for CBS is being done by the same company that cast Arrow and The Flash. Being that Greg Berlanti is involved, the choice seemed obvious. So what are they looking for? According to TVLine they are currently casting two parts – Kara Zor-El (Kara Danvers) and her older foster sister Alexandra "Alex" Danvers.
For Kara Zor-El aka Kara Danvers, the show is eyeing Caucasian females, age 22 to 26, to play 24. As the series' mythology goes, Kara at age 12 was sent from her dying home planet of Krypton to Earth, where she was taken in by the Danvers, a foster family who taught her to be careful with her extraordinary powers. After repressing said skills for more than a decade, Kara is forced to bust out her super moves in public during an unexpected disaster. Energized by her heroism for the first time in her life, she begins embracing her abilities in the name of helping the people of her city, earning herself a super moniker along the way.
The other lead role currently being cast is that of 26-year-old Alexandra "Alex" Danvers, Kara's gorgeous, brilliant, science-minded foster sister. Growing up, Alex was partly jealous of her sibling yet also fascinated by her abilities, prompting Alex to learn as much as she could about alien anthropology, sociology and culture. Today, Alex works for a secret government organization and, alongside her heroic sis, will face many challenges, both mundane and super.
Berlanti wrote the pilot script with Ali Adler (No Ordinary Family) and the two will executive produce the series along with Sarah Schechter.
